The story centers on an elderly hibakusha, whose husband was one of 80,000 human beings killed in the 1945 atomic bombing of Nagasaki, caring for her four grandchildren over the summer. She learns of a long-lost brother, Suzujiro, living in Hawaii who wants her to visit him before he dies.

This film follows the daily lives of a group of people barely scraping by in a slum on the outskirts of Tokyo. Yet as desperate as their circumstances are, each of them—the homeless father and son envisioning their dream house; the young woman abused by her uncle; the boy who imagines himself a trolley conductor—finds reasons to carry on.

A woman looks after her father in law.

When a narcotics deal goes sour and a suspect disappears, leaving only his clothes, Tokyo police question his wife and stake out the nightclub where she works.

Tashiro coincidentally meets his best friend Sugimoto in a bar very close to the apartment in which Sugimoto’s wayward wife is found dead. Although Tashiro is not a suspect in the police investigation, he is racked with guilt and confesses to his wife, Masako. In an effort to further relieve his tortured sense of guilt, he then confesses to Sugimoto. Neither his wife nor his friend can believe that he could have been involved.
